limited slip ?

How much torque should it take to slip a limited slip diff? Is it ok if I can do it by hand with some effort(one wheel on the ground one in the air)

[updated:LAST EDITED ON 05-Dec-02 AT 01:57 PM (EST)]Well it depends on what type of LSD you have. Most factory types with fiber plates should hold 150 ft lbs at the axle. However Detroit Lockers and so called co-co clock type need some torque input from the drive shaft to lock there not easly tested in the air.

I'll check my MOTOR'S truck manual tonight and see if it list the break-a-way torque for the f100.

If I use both hands and grunt I can get it to slip. I'd guess its up around 100ft.lbs. judging from torquing wheel lugs by hand for years in tire shops

Okay I found the book. Motor's trucks 62-72
It list only one type for fords in that time frame. It shows fiber plates and steel plate and the force is applied from a bellevile washers (think washer but dished center to form a cone)
"Ignore the torque required to start the side gear turning. The torque reguired to keep it moving steadily should be between 155 and 195 lb ft" then it calls for LSD type oil.
Thos waher springs do where out and the fibber plates to.

Best of luck

This carrier I have looked ok but used it was free so I'm not going to complain. I will however be getting new guts for it before too long. I have to replace the clutch I grenaded yesterday first.
